Application fi September 28, 1900. Serial No. 31,868. (No model.)

The tank is provided with a number The partition 36 is closed at the top by a roof of concentric partitions or tubes 10, 12, and 39 and provided with openings 40, surround- 13 of larger size surrounding the central pipe ing its lower edge and forming a communica- 6 and dividing the space between it and the tion between the compartments 37 and 38. wall of the tank into a number of distinct In the central opening of the top of the tank I00 compartments 14, 15, 16, and 17, every alter-. 5 is fitted a pipe 29, which extends upwardly nate tube or partition, beginning with the into the tank 21 and downwardly into the main tank or reservoir 5. A skeleton frame composed of outer and inner rings 30 and 31, connected by spider-arms 32, is located in the tank 21, below the roof 39 of the partition 36. The inner ring 31 of the skeleton frame is fitted over the top of the pipe 29, which supports said frame in position. A strainer 33, composed of cheese-cloth or other suitable material, is fastened to the skeleton frame by rings 34 and 35, which clamp the outer and inner edges of the strainer, respectively, the one being outside the ring 30 and the other inside the pipe 29.

As shown in the drawings, (see Fig. 4,) a reservoir 41 is supported above the filtering and oil-extracting apparatus, into which the feed-water from the pipe 42 is forced in the form of spray, where it becomes heated by the exhauststeam from a pipe 43, which steam is in turn condensed, the condensed steam and heated feed-water being discharged by way of a pipe 44, connecting the bottom of the reservoir 41 with the top of the receptacle 23 of-the filtering apparatus. The reservoir 41 is provided with an outlet 45 for the escape of the uncondensed exhaust-steam. As the water containing the oil and other impurities enters the receptacle 23 it passes through the filtering material 28, through the strainer 25, through the filtering stratum 27, through the strainer-bottom 24 to the roof 39 of the partition 36, and thence into the compartment 37, through the openings 40 around the bottom of said compartment into the compartment 38, and up through the strainer 33 and down through the tube 29 to the hood l3 of the tube 13. The upper part of the tube 13 is surrounded by a concentric partition 46, which rests upon the diaphragm 18 and is provided with openings 46 around its bottom, through which the liquid passes into the upper portion of the compartment 14 of the main tank. The water and oil lines are indicated at A and B, respectively. When the oil reaches the level indicated by the line B, it passes off through an open faucet 20. A faucet or cock 20, located below the fancet 20, is normally closed, being used only when it is desired to draw ofi oil from a point below the faucet 20. By reason of the partition 46 all the water is forced beneath the normal plane of the oil, thus preventingany water from becoming mixed with and drawn off with the oil, as might occur if the liquid from the pipe 29 were discharged directly into the oil in the compartment 14 of the main tank. After passing through the opening 46 the oil rises to the top, while the water passes downwardly through openings in the bottom of the tube 13, upwardly through the compartment 15, downwardly through the compartment 16 through the openings in the bottom of the tube 10, upwardly through the compartment 17 and downwardly through the tube 6, and thence by way of the conduit 7 to the tank 8. While passing through the various compartments in the tank 5, the water is relieved of its impurities other than oil by sedimentation.

The tubes 6, 10, 12, and 13 are connected with the outer air at their extremities to prevent siphonage by a vent-tube O, inserted in an opening formed in the hood 13 of the tube 13. An additional diaphragm 18* is attached to thet-ube13belowthediaphragm18. These diaphragms have a tendency to overcome the movement or agitation of the liquid in the tank, whereby the efliciency of the apparatus is enhanced, and particularly when the device is used on movable structures, as steamships.

In forming the openings 40 in the partition 36 the material is cut out and turned inwardly,formin.glips36. (SeeFig. 5.) These lips divide the liquid as it passes upwardly into the compartment 38 and facilitate the separation of the oil from the water.

Having thus described my invention, what I claim is 1. The combination with an oilextractor having an opening in its top, of a filtering apparatus comprising a tank mounted above the oil-extractor, and provided with a pipe passing through the opening in its top, said pipe being open at both ends, a skeleton frame mounted on said pipe, a strainer attached to the said frame, a partition surrounding said frame, resting on the bottom of the tank and having openings in its lower edge, its top being closed, a space being left in the tank around said partition, and a quantity of filtering material supported in the tank above the top or roof of said partition.

3. The combination with an oil-extractor having an opening in the top of its casing, of a filtering apparatus comprising a tank mounted on top of the oil-extractor casing, an open-ended pipe inserted in the opening in the top of said casing, a skeleton frame mounted on top of said pipe, a strainer fast on said frame, a partition surrounding said strainer and projecting above the top of the pipe, said partition being closed at the top and having openings at its lower edge, a space being left between the partition and the Wall of the tank, and a receptacle supported in the tank above the roof of the par- IIO tition and having astrainer-bottom supporting a quantity of filtering material.

4. The combination with an oil-extractor having an opening in the top of its casing, of a filteringapparatus com prising a tank mounted on top of the oil-extractor casing, an openended pipe inserted in the Opening in the top of said casing, a skeleton frame mounted on top of said pipe, a strainer fast on said frame, a partition surrounding said strainer and projecting above the top of the pipe, said partition being closed at the top and having openings at its lower edge, a space being left between the partition and the wall of the tank,and two receptacles mount ed in the tank above the roof of the partition, each having a strainer-bottom, one receptacle being located within the other, a suitable space being left between them, and a quantity of filtering material in each receptacle.

5. In an oil-extractor, the combination with a main tank containing a central outlet-tube and a tube surrounding said outlet-tube and having a hood at the top, of a diaphragm surrounding and attached to the last-named tube in the upper portion of the tank, a space being left between the said diaphragm and the wall of thetank, and a concentric partition surrounding the upper portion of the tube, projecting above its hood, extending below the oil drawn oif level in the tank and resting upon the said diaphragm, the top of the tank being provided with an inlet-opening located above the hooded tube.

6. In an oil-extractor and filtering apparatus, the combination with a main tank containing a central outlet-tube and a tube surrounding said outlet-tube and having ahood at its top, a diaphragm surrounding and attached to the last-named tube in the upper portion of the tank, a space being left between the said diaphragm and the wall of the tank, a concentric partition surrounding the upper portion of the tube, projecting above its hood,
